    Yes, they work well. More accurate/dependable than any digital/electronic vacuum indicater you can buy. JMHO
    Your poor planning does not constitute an emergency on my part!!!!

    Its a wet bulb vacuum indicator. There is a thermometer in it that is wetted with vacinol. The lower the vacuum, the lower the bioling/evaporation point. 38F is around 6000 microns. There is a chart that relates the temp vs vacuum.

    Never seen 'em at the supply house...............

    Who has them? Abco maybe?

    Or online/special order only?

    Would like to take a closer look.

    Got to email the guy to get delivery and price info. None of the supply houses sell this. Its been around forever, long before electronic ones. All the York books show it in their evacuation procedures.

    I've had 3 over the years, although mine were made by Humphreys. Good gauges, work with distilled water or vacanol. 35* with distilled water is 5000 microns, -12* on vacanol is 5000 microns. Best to use vacanol or you can't go deep (obviously).

    That's the ticket

    Please read my post on vacuum readings thread. I've seen this device in action on a large system, estimated cost is about $150.00, not bad when when you consider the cost of an accurate electronic meter.-GEO
